3M 5200 Adhesive Sealant creates a waterproof permanent bond and seal. 3M now offers a 4200 for a less permanent seal and a 4000 for more cosmetic seal. All these and other 3M products are available at www.westmarine.com
*A lot less strong....hmmmm, does he mean tensile strength? Or sheer strength? And Isn't the most obvious differentiating feature of the fast cure 4200 product that it is "fast cure" more so than the fact that is has less strength than the 5200 although that is undoubtedly true. I thought that the most outstanding difference between the 5200 and the 4200 is the fact that the 5200 has a long cure time (up to 7 days to fully cure?) whereas the 4200 cures in a matter of a few hours which makes it more suitable for quick repairs that require a quick turnaround time in the boat repair yard. Just my two cents worth picked up from watching other videos on RU-vid. I thought there was quite a bit missing from his summary of the differences between products.
The biggest debate is , explaining the best uses for 4200 and 4000 meaning what is not recommended. Meaning they say cosmetic for 4000 or accessories so meaning can I use to get nice seal for my gauges or instrument cluster and will it be able to be removed same as 4200 . I hear legit 50/50 on this subject.
You can check out this guide on using sealants! www.westmarine.com/WestAdvisor/How-to-Select-Sealants-and-Caulk It helps explain the different usages for each caulk. We hope this helps!
Can I use this to glue the top half of my fiberglass 1969 Barracuda hydrocycle back to the bottom half? The top fits down into a 3/4” lip then gets riveted or screwed with one of those aluminum/rubber strips around the seam. There’s is a video on my channel of the boat, it’s basically a predecessor to a seadoo that takes an outboard motor...so this is kind of a structural application I need, as you sit and steer and hold on to the top half of the boat.
5200 would be a great choice to join these two half of the boat back together. Unless you think you will need to take it apart in the future. 5200 creates a permanent bond that will be nearly impossible to remove once joined. If this is the case then 4200 or 4000 would be a better choice. We hope this helps!
@@WestMarineInc thanks for the reply! Hopefully it will never have to be taken apart again, and if it does it will be by somebody else...imma hit my local west marine in rancho Cordova soon to pick some up, thanks again.
I will tell you what will happen when you buy a small tube, it wont stop coming out, especially if it is warm out, it will pour ALL over make a huge mess and and you have wasted 20 bucks on on an overpriced small tube of garbage. People who dont know caulks will tell you to use it. It is priced by name, it does work well, but as far a consumer friendliness,it is a "cobra" for wasting your money. Do your home work, the same stuff, no name and less known is out there for a 1/4 of the price.
